Question
#include<iostream>
#include<stack>
using namespace std;
void f1(int x);
int f2(int p);
int f3(int n);
int main(){
int a=5;
f1(a);
cout<<endl;
}
void f1(int x){
cout << f2( f3(x)); // B
}
int f2(int p){
int q=f3(p/2);
return 2*q;
}
int f3(int n)
{
return n*n+1;
}
For each of the following, use a sequence of diagrams to trace
the action of the run-time stack with the specified
changes:
1. With a initialized to 5 instead of 3 and f1() replaced by
void fl(int x)
{
cout
Explanation / Answer
1)
#include<iostream>
#include<stack>
using namespace std;
void f1(int a);
int f2(int b);
int f3(int c);
void f1(int x)//error is here you have given fl not f1
{
int result=f3(x) + f2(x + 1);
cout<<result<<endl;
return;
}
int f2(int p){
int q=f3(p/2);
int dq=2*q;
return dq;
}
int f3(int n)
{
return (n*n+1);
}
int main(){
int a=5;
f1(a);
cout<<endl;
return 0;
}
2)
#include<iostream>
#include<stack>
using namespace std;
void f1(int a);
int f2(int b);
int f3(int c);
void f1(int x)
{
int res=f2( f3(x));
cout << res<<endl;
}
int f2(int p){
int q=f3(p/2);
int dq=2*q;
return dq;
}
int f3(int n)
{
return (n*n+1);
}
int main(){
int a=5;
f1(5);
cout<<endl;
return 0;
}
